1.1.31 Calling Party Control (CPC) Signal Detection

Description
A CPC (Calling Party Control) signal is an on-hook indication (disconnect signal) sent from an outside (CO)
line when the other party hangs up. To maintain efficient utilization of outside (CO) lines, the PBX monitors
each line's status and when a CPC signal is detected on a line, the PBX disconnects the line and alerts the
extension with a reorder tone.
Conditions
• CPC Signal Detection is programmable for incoming outside (CO) line calls (
Detection—Incoming) and for outgoing outside (CO) line calls (
Outgoing).
• If a CPC signal is detected during a call between a caller using the DISA feature (
Inward System Access (DISA)) and an extension or an outside party, the call will be disconnected.
• Generally, CPC Signal Detection functions for incoming outside (CO) line calls and does not function
for outgoing outside (CO) line calls. If an extension user remains off-hook after an outgoing outside
(CO) line call is completed, the PBX will not release all the switches used to establish the connection.
The connected outside (CO) line will continue to be in use. To prevent this, CPC Signal Detection can
be programmed to function for outgoing outside (CO) line calls.
